I have an 88 Force 125 motor. when i start it , with the muffs on, it barely spits water. the last time i took the lower unit off i think that i remeber seeing a bolt missing out of the impeller housing . should i try relpacing the bolt before buying a new impeller ? would that cause low water flow ?

Sometimes it's difficult to get a good seal with the muffs on the cylindrical portion of the gear case where the water intake ports are located on that style gear case.

Will a missing bolt cause low water flow? Hard to say. I definitely would get that fixed though.

I am having the same problem with a 98 75hp i was told to check the tube from the pump to the motor.

check and make sure the line is not clogged between the motor and the talltale. If you can remove the line just see if you can blow through it. I have had mine clogged with some plant stuff. I would replace the bolt though. The water pump has a lot of troque and it would be a shame to have to remove 3 sheared off bolts. Is the motor over heating at all?

yes it has over heated ! i found out that the previous owner broke a bolt of so i have to get that out and i think that should fix my problem . there is a lot of pressure in the housing . so i think that when it trys to pump water, because of the missing bolt , it is shooting water out of the side of the water pump housing!
